Would be possible to make filter to fill colors inside enclosed shape?

I have found this image shown below, and is all black and white, and I wonder if there could be a way to make a filter that could be able to fill each of the enclosed shapes with different random colors, or at least with different random grayscale

i know that FF does not have any Flow fill component, and maybe I am asking something impossible, but I wonder if there could be some possible way that FF could recognize the edges and fill the inside of them

Thanks very much

The source image shown here is made with Processing.org software

W Blut Voronoi

or also as said it could be also instead filling with differents shades of gray

Take a look at this thread: https://www.filterforge.com/forum/read...&TID=13353
Apparently this is a tricky problem.

EDIT: Lol, sorry, you actually know about that thread.

thanks skybase and Zoltan, Yes I know that thread thanks

I know it may be a very difficult thing for the software to be able to find the edges of the enclosed shapes and fill them with different colors, and there is no data reference to know where are all these enclosed shapes, and they are all irregular and different, so there is no pattern to follow.

The hand made filling exist since Deluxe Paint in 1985, but this depends on that yourself give the starting point already inside one of the enclosed shapes, and will only detect the edges of only that only shape

i agree that is really extremely tricky and surely is needed some very complex scripts or coding to be able to recognize shapes and able to fill them automatically

Skybase SpaceRay, I don't know if you ever received my PM via FilterForge but I dropped you the possible solution via other programs there.

no, I did not receive it, sorry, maybe I should look for it

Skybase wrote It seems like the only program so far that does this SEEMS to be the one stop solution is Genetica.

Can this be done in Genetica? how do you it? i have Have Genetica 4.0 but regretably I still can not understand how to build things with it, only use it for seamless tiling

Maybe the stuff we did recently in this thread with the bomber is a start? It looks similar to the example picture from Genetica, but is not the same. It seems that the "regions" node in Genetica can find regions of any input (including an image!), whereas our filters only work with regions generated by the bomber component.

Thanks ThreeDee. Right on the money. This point (used up resources due to the procedural nature of FF) shows up elsewhere (with or without LUA): Fractals, reaction diffusion, anti-aliasing (FXAA) among many other examples. Any concept that requires a large bitmap and multiple passes though the data are going to be slow. I know, I have coded fractals and reaction diffusion with the resulting time to go to dinner

I kinda think the whole situation of needing to fill a lot of empty regions for whatever reason is kinda niche in its own way. Usually when you're confronted with a complicated task, you have ways of handling that from the start. In such a case you'd construct things so that you don't run into problems like that. So to me, stuff like "Now I need to fill holes with random colors (i.e.)" is an after-thought.

Example image from Genetica using the image above. Damn. That's impressive. It's a bit messy but it works. The anti-alias clearly got in the way of Genetica but I guess you can reapply anti-alias later using some other tool. It even nailed the little tiny areas.

[Edit] Then again I'm wondering why go through the trouble lol.

SpaceRay Or if you know any other software that could be able to do this with a GUI based thing without scripting or programming as it happens with processing

As I knew that would be complex and difficult in FF, is why I wrote this as an alternative, and so it seems that the alternative is Genetica 4.0

WOW, WOW! How have you done that with Genetica??? do you have the gtx file that makes this possible?

It looks good and interesting, well done, congratulations

How many colors can be used and how are they distributed?

ThreeDee I believe we've covered this before: It is possible with scripting, but due to FF being procedural, not pixel-based, it will be extremely inefficient

Thanks for explaining in this good way why is very complex and difficult to do it in FF, I understand it.

But then you have wrote a possible alternative way to do try to find a way to do it in some way??

ThreeDee That out of the way, an interesting potential approach to the problem occurred to me. The filter only has to do one thing: create a grayscale image with a different index value for each region. What if the procedure were to be broken down to two passes: 1) Find the regions inside each rendering thread only -- either an 8 x 8 grid or 16 x 16 grid, which is how FF break the image down for multithread rendering -- and give each region an index value. Apply and save this file. 2) Open this intermediate file and use a second pass filter to find any border areas wh ere two index values should be the same and make them so. Both steps would have to be scripted, but this would be at least 64 or 256 times more efficient than trying to do it all in one go. Just saying.

i have no idea how to make this, would this be possible and work in some way?

This happens if YOU are the one that is creating yourself that black and white shape, that you know that you will need to fill the regions with colors and have to plan ahead how you are going to do it, and not do it and then think later how you are going to do it, so I agree that you have to think about that from start

But if you have a software that is able only to draw the black and white shapes as it happens with FF but is not possible to fill them because this software does not have any possible way to fill that regions and holes, you have to search for another posible solution.

Beautiful and lovely colorful example you have here in the post above, like it very much, and the color compositions and distribution is well done and balanced, and is well done the random that is not repeated much on near shapes, good.

Oh, it seems that it may be simple to use. I will try to see how it works, thanks for the link.

Spaceray, I got the PM and sent a response to the email listed for that private message about a week back. This forum message is the only way it seems I can reach you for now. I got another message today so I thought I'd notify here.
